- 1. Peanut Butter – 1 cup (smooth or crunchy)
Peanut butter is the star ingredient in this recipe. Choose the type that you prefer, whether it’s smooth or chunky, both will give the cookies a rich peanut flavor.
- 2. Brown Sugar – 1 cup (packed)
Brown sugar adds sweetness and moisture to the cookies, along with a hint of caramel flavor. Be sure to pack it firmly in the measuring cup for accuracy.
- 3. Egg – 1 large
The egg helps bind the ingredients together and contributes to the soft texture of the cookies.

Step-by-Step Guide to Making 4-Ingredient Peanut Butter Cookies
Making 4-ingredient peanut butter cookies is quick and easy! Here’s a simple step-by-step guide to help you bake perfect cookies in no time.
1. Preparing the Ingredients
Before you start, make sure you have everything you need. Measure out your ingredients and make sure your peanut butter is at room temperature. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper or a silicone baking mat.
2. Mixing the Ingredients
In a large mixing bowl, combine the 1 cup of peanut butter, 1 cup of brown sugar, 1 egg, and 1 teaspoon of baking soda. Use a spoon or a hand mixer to mix everything together until smooth. The dough should be thick and slightly sticky, but still easy to work with.
3. Shaping the Cookies
Once your dough is ready, scoop out small portions of it using a spoon or your hands. Roll each portion into a ball about 1 inch in diameter and place them on your prepared baking sheet. Leave about 2 inches of space between each cookie.
4. Pressing the Cookies
Take a fork and gently press down on each cookie ball to create a criss-cross pattern. This step not only makes the cookies look more traditional but also helps them bake evenly.
5. Baking the Cookies
Bake the cookies in your preheated oven for 8-10 minutes or until the edges turn golden brown. Keep an eye on them, as they can bake quickly depending on your oven. If you prefer softer cookies, remove them from the oven when they are just golden at the edges.
6. Letting the Cookies Cool
Once the cookies are done, remove them from the oven and let them cool on the baking sheet for a few minutes. After that, transfer them to a wire rack to cool completely. This helps them firm up and prevents them from breaking.

Tips and Tricks for Perfect Peanut Butter Cookies
To ensure your 4-ingredient peanut butter cookies turn out perfectly every time, here are some helpful tips and tricks:
1. Adjusting Consistency with Different Peanut Butters
Not all peanut butters are created equal. Some are runnier than others, which can affect the consistency of your cookie dough. If your peanut butter is very runny, you can add a little extra baking soda or a small amount of flour to help thicken the dough. On the other hand, if you’re using a thicker peanut butter, you might need to soften the dough with a tiny bit of milk.

2. Perfect Bake Time for Soft vs. Crunchy Cookies
The baking time is key to getting the texture you want. For soft and chewy cookies, take them out of the oven when the edges are golden, but the center is still soft. If you prefer crunchy cookies, let them bake for an extra minute or two, until they are evenly golden throughout. Make sure not to overbake, as they can become too hard.
3. Don’t Overmix the Dough
When mixing your dough, be sure to stir just until the ingredients are combined. Overmixing can lead to dense cookies. Gently mix the ingredients to avoid incorporating too much air or developing the dough too much.
4. Store Your Peanut Butter Cookies Properly
To keep your cookies fresh, store them in an airtight container at room temperature. They will stay soft for about a week. If you want to keep them longer, you can freeze them. Place the cookies in a freezer-safe bag or container, and they will last for up to three months. Simply thaw at room temperature for a few hours before eating.
5. Try Different Types of Peanut Butter
Feel free to experiment with different types of peanut butter. Natural peanut butter can give the cookies a slightly different flavor and texture. You may need to adjust the amount of sugar depending on how sweet the peanut butter is.
6. Chill the Dough for Better Results
If you have a little extra time, chill the cookie dough for 30 minutes before baking. Chilling helps prevent the cookies from spreading too much while baking, giving them a thicker, more substantial texture.
By following these tips, you’ll be able to create the perfect batch of peanut butter cookies every time!

Flavor Variations: How to Add Your Own Twist
While the classic 4-ingredient peanut butter cookie recipe is delicious on its own, there are plenty of ways to customize the flavor and create a unique twist. Here are some fun variations you can try to elevate your cookies:

1. Add Chocolate Chips
If you love the combination of peanut butter and chocolate, try adding chocolate chips to your dough. Stir in about 1/2 cup of semi-sweet or milk chocolate chips before baking. The gooey chocolate will melt into the cookies, creating a delightful treat!
2. Mix in Chopped Nuts
For an extra crunch and to amplify the peanut flavor, chop up some peanuts or any nuts of your choice. Add 1/4 to 1/2 cup of chopped nuts to the dough. Walnuts, almonds, or pecans also work well if you want to mix things up a bit.
3. Spice It Up with Cinnamon
Cinnamon adds a warm, cozy flavor to peanut butter cookies. Simply add 1/2 teaspoon of ground cinnamon to the dough along with the baking soda. The spice pairs beautifully with the sweetness of the brown sugar and the richness of the peanut butter.
4. Try a Salted Peanut Butter Version
For a salty-sweet contrast, use salted peanut butter instead of regular peanut butter. This brings a savory edge to your cookies. You can also sprinkle a pinch of flaky sea salt on top of the cookies just before baking to enhance the salty flavor.
5. Add a Touch of Vanilla
For a more aromatic and rounded flavor, add 1 teaspoon of vanilla extract to your dough. It will complement the sweetness of the brown sugar and add a lovely fragrance to your cookies.
6. Mix in a Little Coconut
If you like the tropical flavor of coconut, stir in about 1/4 cup of shredded coconut to the dough. This will give your cookies a slight chewiness and a sweet, nutty flavor that pairs wonderfully with peanut butter.
7. Make It Peanut Butter and Jelly
Turn your peanut butter cookies into a fun twist on the classic peanut butter and jelly sandwich. Once the cookies are baked and cooled, spread a thin layer of your favorite fruit jam or jelly between two cookies to create a delicious sandwich.
Feel free to experiment with these variations to find your favorite combination. Whether you add chocolate, nuts, or spices, you’ll be able to create a batch of cookies that’s truly your own!
Common Mistakes to Avoid When Baking Peanut Butter Cookies
While peanut butter cookies are simple to make, there are a few common mistakes that can affect the texture and flavor of your cookies. Avoiding these errors will help ensure your cookies turn out perfectly every time!
1. Overmixing the Dough
One of the biggest mistakes when baking cookies is overmixing the dough. When you mix the ingredients too much, you incorporate too much air and develop the gluten, which can result in dense, tough cookies. Mix your dough just until the ingredients are combined for soft, chewy cookies.

2. Not Preheating the Oven
Preheating your oven is crucial for even baking. If the oven isn’t hot enough when you place your cookies inside, they may spread too much and become flat. Be sure to preheat your oven to the correct temperature (350°F or 175°C) before you start baking, and always allow it to fully reach the set temperature before placing your cookie sheet inside.
3. Using the Wrong Type of Peanut Butter
Not all peanut butters are created equally, and the type you choose can affect the texture of your cookies. Natural peanut butter (which contains more oil) can make the dough too runny, while thick peanut butter may result in overly dense cookies. Stick to regular, creamy peanut butter (without added sugar or oil) for the best results.
4. Overbaking the Cookies
If you leave your cookies in the oven for too long, they can become dry and hard. Peanut butter cookies bake quickly, so keep an eye on them and check for doneness when the edges turn golden brown. For soft cookies, pull them out as soon as they’re golden around the edges but still slightly soft in the center.
5. Skipping the Fork Criss-Cross Pattern
The fork criss-cross pattern on top of the cookies isn’t just for decoration—it helps the cookies bake evenly. If you skip this step, your cookies may not spread as evenly and may not achieve the right texture. Don’t forget to press down lightly on the dough with a fork before baking!
By avoiding these common mistakes, you’ll be on your way to baking the perfect peanut butter cookies every time.
Frequently Asked Questions (FAQs)
1. What can I substitute for brown sugar in this recipe?
